BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device, and more particularly to an image display device that can provide different artifacts and the like to observers at different viewing positions. [Prior Art] Conventionally, a two-dimensional display device that displays three-dimensional stereoscopic images and a dual-screen display device that provides different images to observers at different viewing positions are known. Further, in the related art, a stereoscopic display device for displaying a three-dimensional stereoscopic image has been proposed in the form of a parallax screen $. Such an image display device is disclosed in, for example, Japanese Patent Laid-Open No. 2857429. In the above-mentioned Japanese Patent No. 2857429A, it is disclosed that an electronic parallax barrier disposed on the observer side is controlled by a control means such as a microcomputer, thereby being at a predetermined position of the electronic parallax barrier. The opening of the predetermined shape and the shading = a three-dimensional image display device formed into a long shape. Further, in the three-dimensional image display device disclosed in Japanese Patent No. 2857429A, when a three-dimensional imaging is provided to an observer, the left-eye imaging image is incident on the observer's left eye and the right eye. The opening of the electronic parallax barrier is formed by injecting an image into the right eye of the observer. In addition, it is provided to the observer that the dimensional (planar) drawing control is such that all the areas of the electronic parallax barrier are formed as an opening portion, and all the images can be projected on the eyes of the observer. In addition, it is proposed that the barrier layer provided with the slit-shaped opening portion and the light-shielding portion is disposed on the observer side of the display panel, and the 317823 5 , 1281554 can be observed at the position of the same place. The device provides a double-faceted display device for different images. Fig. 26 is a plan view showing the principle of the double-faceted display splitting of a conventional example. The configuration of the double-sided display device 500 according to the conventional barrier mode will be described below with reference to Fig. 26. As shown in FIG. 26, the conventional double-face display device 500 according to the barrier method includes a display panel for displaying an image, and a polarizing plate disposed on the side of the viewer 51〇 and 52 of the display panel 5〇1. 5〇2, and configuration; the barrier layer 503 of the spectator 51 and the 520 side of the polarizer 502. In addition, the display panel 501 is alternately disposed in a direction orthogonal to a connecting line substantially opposite to the left eye 51〇a (520a) and the right eye 51〇b (520b) of the viewer 510 (520) ( The glass substrate 5〇1\ which is perpendicular to the paper surface of Fig. 26, in addition to the display panel 5〇1, is made of glass (refractive index nl, 153) of the applicator = A (about 0.5 mm). In addition, in the pixel row 5〇u, the display is used to allow the observer to: view the image L1 of the second view, and display the image R1 for the #watcher 20 to view in the pixel row 5〇lb. . Further, the pixel row 5Qia and the pixel row 5〇ib have pixel pitches B (about 〇 6 mm), respectively. Further, the polarizing plate 5〇2 is composed of a resin having a thickness c (about 〇lmm) (refractive index is used). Further, in the barrier layer 503, a light for emitting the display panel is provided. The light-shielding portion 5〇3a and the opening portion 5〇3b for allowing the display panel to be exposed to the light of the display panel. The light-shielding portion 5a and the opening portion 5〇3b are connected to the pixel row 501a and the pixel row of the display panel 501. 5〇lb is perpendicular to the line connecting the left eye 51〇a (52〇a) 3]7823 6 •1281554 * and the right eye 51艮b (520b) of the observer 510 (520). The direction (perpendicular to the direction of the paper surface of the %th image) is extended. Further, the light shielding portions 5〇3& and the opening 邰 503b correspond to the pixel rows % & and pixel rows 5+ by the display panel 5〇1 In addition, the barrier layer is provided with: the light-shielding portion 503a of the barrier layer 503 limits the emission angle of the light emitted by the pixel row of the display panel 5〇1 and the pixel row 501b Next, refer to the 26th item to explain the double-sided display of the conventional double-sided display device. In the conventional double-face display device 500, when the viewer 51 passes through the opening 503b of the barrier layer 503 and views the display panel from the position where the distance display panel 5〇 is the observation distance D (600 mm), Observer Η The image u displayed by the pixel row 5Gla of the display panel 5 () 1 is observed. Further, the observer 520 observes the distance from the display panel 501 via the opening 5 〇 3b of the barrier layer 5 〇 3 . When the panel 5〇1 is viewed at the position of D_mm), the observer 52 observes that the pixel of the display panel 5〇 is displayed as the image R1 displayed by 501b. Thereby, observers 51 〇 and 52 位于 at different observation positions can be observed within the range of observation range, and different portraits can be observed separately. ', in the conventional double-sided display device shown in Fig. 26, the observation range о E of the observers 510 and 520 can satisfy the following (1) from the similar relationship between the triangles 55 〇 and 56 ' formula. D : (C/n2)+(A/nl)-E : B.........(1) Change this equation (1) to the equation for obtaining the observation range E, and obtain the next 317823 7 -1281554 " Column (2). E 2 (Bx D) / {(C / n2) + (A / nl)} ... (2) can be known from equation (2) The observation range e is proportional to the pixel pitch β of the display panel 5〇1 (affected by the pixel pitch B). B'.06mm, D: 600mm, C=0.lmm, A=0.5mm, 53, n2 1.49 is substituted into the above formula (2), and E=9i 4 (mm). That is, in the conventional double-sided display device 5 (8) shown in Fig. 26, the pixel pitch B is used. When the display panel 501 of 〇6 mm), the observation range E of the observers 51〇 and 520 Lu is about 91.4 mm (9.14 cm). However, the conventional double-sided display device shown in Fig. 26〇〇 In the meantime, since the viewing range E is proportional to the pixel pitch β of the display panel 501 (affected by the pixel pitch B), if the pixel pitch β of the display panel 5 〇 1 is small, the observation range E is also reduced. For example, if the pixel pitch β of the display panel 501 is less than 0.06 mm, the observation range E of the observers 51〇 and 520 is small. 9.14 cm, making it difficult for the observers 510 and 520 to observe φ. Therefore, in the conventional double-sided display device 5A shown in Fig. 26, it is difficult to use the high-definition display panel 501 having a small pixel pitch B. As a result, it is difficult to provide a problem of high-definition artifacts for the observers 51〇 and 520 located at different observation positions. Further, the barrier layer 503 is disposed on the side of the viewer 5 1 〇 and 5 2 of the panel 5 01 Therefore, a part of the light emitted from the display panel 501 is shielded from light by the light blocking portion 503a of the barrier layer 503. As a result, the brightness of the artifact observed by the observers 510 and 520 is lowered to form a problem that the book image becomes dark. In the three-dimensional image display device of the above-mentioned Japanese Patent Publication No. 2 δ57429, the image display surface is equipped with a type parallax barrier: the image is emitted from the image display surface and is electronically displayed. The light-shielding portion of the parallax barrier is shielded from light: the brightness of the image observed by the observer is lowered, and thus the change is made::: [Invention] The present invention has been made to solve the above problems, and the present invention resides in For the purpose of achieving the above purpose, the observers at different viewing positions can be viewed differently without lowering the artifacts observed by the observer.

At this time, the light incident on the polarization control region 7a of the polarization control liquid crystal panel 7 penetrates without changing the polarization axis, and enters the polarization control region 7b of the polarization control liquid crystal panel 7 on the other hand. The light beam is emitted when the polarization axis substantially produces a change of =0 (with the second polarization axis). As shown in the second diagram of the rear view, the second polarization state is obtained. Light emitted by the polarization control area 7a By the cylindrical mirror 8, the light is collected by looking toward the observation direction = 10.

The plate 6 passes only the light having the polarization axis of the 317823 26 1281554 and travels toward the polarization control liquid crystal panel 7. Thereafter, the light having the first polarization axis passes through the polarization control of the polarization control liquid crystal panel 7. The region 7a and the polarization control region 7b. At this time, the polarization control of the polarization control liquid crystal panel 7 is incident. The light of the region 7a penetrates without change of the polarization axis. On the other hand, the light incident on the polarization control region 7b of the polarization control liquid crystal panel 7 is substantially 9 〇 on the polarization axis. After the change (with the second polarization axis) is emitted, the light emitted from the polarization control region 7a in the state having the first polarization axis is directed to the observers 10 and 2 by the cylindrical mirror 8.

Further, the light emitted from the polarization control region in a state of having the second polarization axis substantially perpendicular to the ith polarization axis is performed by the column The mirror 8 is condensed in such a manner that the right eye 1 〇 & and 20 a toward the viewer 1 〇 and 2 行进 。 # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # 聚 聚Light rays traveling from the left eye 10a and 2〇a of 10 and 20 are incident on the phase difference plate 9 having the penetrating region 9a and the polarizing region 9b. Thereafter, the light having the first polarizing axis is penetrated by the phase. The penetrating region 9a of the difference plate 9 and the polarizing region 9b. At this time, the penetrating region penetrating the phase difference plate 9 For example, the light beam penetrates without changing the polarization axis, and the light incident on the polarization region 9b is substantially 9 〇 in the polarization axis (with the second polarization axis) After that, the light emitted from the penetration region % of the phase difference plate 9 and directed to the left eyes 10a and 2a of the observers 10 and 20 is incident on the display panel 2 in the state having the second polarization axis. And the polarizing plate 4 disposed between the phase difference plates 9 and directly penetrating the polarized light 317823 27 • 1281554 and 2〇a cannot view the right eye image R3 displayed by the pixel row 2b of the display panel 2. Therefore, As shown in Fig. 9, the left-eye sputum image L3 of the display panel 2 is incident on the left eye 1 〇a and 20a of the observer 1 。. The pixel row 2a of the display panel 2 is incident. On the other hand, in the state of having the second polarization axis orthogonal to the first polarization axis, the left eye (7) a 2 20a of the phase difference plate 9 is emitted from the polarization region 9b of the phase difference plate 9 toward the observer 1〇 and 2〇. The light is incident on the polarizing plate 4 provided between the display panel 2 and the phase difference plate 9, and is absorbed.

After that, the display of the left eye and the right eye are displayed every 1/120 second. In the above configuration, as shown in FIGS. 12 and 13 , the left-eye image L4 displayed in the pixel row of the display panel 2 is incident between 〇/12〇 and 1/120 second. The observer's left eye 1〇& and 2〇& In addition, the right-eye image R4 displayed on the pixel row 2b of the display panel 2 is incident on the right eyes 10b and 2〇b of the observers 10 and 20. Thereafter, between 1/12 〇 and 2/120 sec, since the polarization control region 7a and the polarization control region 7b of the liquid crystal panel 7 are controlled by switching the polarization, the left eye 1 toward the viewers 10 and 20 is controlled. The light rays of 〇a and 2〇a are controlled by the polarization control region 7b of the liquid crystal panel 7 through the polarization control, and are caused to travel toward the phase difference plate 9 in a state where the polarization axis substantially changes by 90. At this time, since the left-eye 昼 image L4 and the right-eye 昼 image R4 displayed by switching the pixel rows 2a and 2b of the display panel 2 are controlled, as shown in FIG. 13 317823 32 1281554, Yu 〇 2 Between /12 sec., the left-eye 昼 image L4' displayed on the pixel row η of the display panel 2 is incident on the left eye 10a and 20a of the viewer 1 〇 and 2 ,, and the pixel row 2a of the display panel 2 The right eye image R4 is displayed on the right eye 1汕 and 2 of the observer 1〇 and 2〇.
